ROLLING-DISK 'CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 769,822, datedSeptember 13, 1904,

Application filed April 18, 1904, Serial No. 203,729. (No model.)

To a. whom, it may concern.-

Be it known that I, HENRY BRUCE FURR, a citizen of the United States,residing at Day-' ton, in the county of Lasalle and State of Illinois,have invented certain new and useful Improvements in Rolling-DiskCultivators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to rolling-disk cultivators.

The object of the invention is to provide a machine of this characterwhereby the soil may be cultivated to a greater or less degree, ascircumstances may require, and to provide means whereby the position ordirection of the disks may be changed while the machine is in motion.

A further object is to provide means whereby the disks may be raised andlowered to regulate the cut of the same and to raise them above theground.

WVith these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described, and particularly pointed out in theappended claims.

In the accompanying drawings, Figure 1 is a side elevation of themachine constructed in accordance with the invention. Fig. 2 is a topplan view of the same. Fig. 3 is a rear view. Fig. 4 is a detailvertical transverse sectional view on the line i i of Fig. 1. Fig. 5 isa horizontal sectional view, taken above beams. Fig. 6 is a detail viewsimilar to Fig. 4:, showing a modified construction of the parts shownin that figure. Fig. 7 is a detail sectional view of the lower end of adiskstandard, showing a modified means for connecting the hub of thedisks to said standard. Fig. 8 is a detail horizontal sectional Viewshowing a double hub arranged on the lower end of a standard, wherebytwo disks may be carried by one standard. Fig. 9 is a detail verticalsectional view of the lower end of a standard and a disk-hub, showingthe manner in which the same may be lubricated.

Referring more particularly to the drawings, 1 denotes a main frame,consisting of longitudinal side bars 2, the forward ends of which aresecured to bars 3, which converge and are bolted to the inner end of atongue 4:. The rear ends of the side bars are connected by a cross-bar5, on which is mounted the drivers and operators seat 6. The rear endsof the converging bars3 are bent inwardly at an angle to the frontportions thereof, and to said rear ends is bolted a cross-bar 7, whichextends between the side bars 2. To the cross-bar 7 are bolteddownwardly-projecting brackets 8, in which are secured the upperhorizontal portions. of right-angularly bent axles 9, on the lower endsof which are formed spindles on which are journaled thesupporting-wheels 10. Suitable brace-bars 12 extend from the lower orspindle end of the axle to the frame 1 to securely brace and hold theaxles against movement. On the inner end of the tongue 4 is secured anupwardly-projecting bracket 13, in which is pivoted a doubletree 14, tothe ends of which are pivoted short depending rods 15, to the lower endsof which are connected draft-chains 16, which pass under grooved pulleys17, journaled in hangers 18, secured to the outer ends of atransversely-disposed bracket 19, which is secured to the under side ofthe tongue 1. On the ends of the draft-chains 16 are connectedswingletrees 20.

Arranged beneath the frame 1 are a pair of disk-supporting beams 21,which are adjustably secured to the lower ends of front and rear archedbars 22 and 23, the lower ends of which are bent outwardly at rightangles and pass through clips 24, secured to the beams 21. Set-screws 25are screwed through the clips 24 and engage the bent ends of the archesand hold the beams in their adjusted positions thereon. The front archedbar 22 is secured directly to the forward ends of the beams; but therear arched bar is secured to rearward extensions 26 of the beams, asshown.

The beams 21 are preferably in the form of an obtuse angle, and eachconsists of upper and lower fiat parallel bars which are connectedthereon a beveled pinion 39.

together and spaced apart by bolts 27, on which are arranged sleeves 28.The forward ends. of the beams are pivotally connected to the lower endsof upwardly and forwardly curved bars or arms 28, which are connected attheir upper ends to the ends of a yoke 29, which has at its forward enda universal-joint connection with an adjustable head 30, which isslidably mounted on an upright post or bar 31, secured at its upper endto the lower side of the tongue 4 and at its lower end to a bracket 32,which is bolted to the lower side of the tongue and to a transverse bar33, secured between the converging bars 3 in rear of the inner end ofthe tongue 4.

The head 30 consists of upper and lower blocks 34, having formed intheir meeting faces at the rear end sockets 35, which are adapted toreceive the ball member 36 of the joint which is secured on the yoke 29.The forward portions of the blocks are provided with vertical alinedholes, by which they areslidingly engaged with the post or standard 31.The blocks 34 are held together on the post by a clip 37, on the forwardside of which is formed a lug or nut having a verticallydisposedthreaded aperture which is engaged with a vertically-disposed threadedrod or bolt 38, the upper end of which passes loosely through a hole inthe tongue 4 and has fixed The lower end of the rod passes through thebracket 32 and has on its lower end a retaining nut 40. Meshing with thepinion 39 is a similar pinion 41, fixed on the end of arearwardly-extending inclined rod 42, the forward end of which isjournaled in a bracket 43, secured to the tongue, and the rear end ofwhich is suitably supported and provided with a crankhandle 44. Upon theturning of the crankrod 42 the threaded rod or bolt 39 will be turned,which will cause the head 30 to be moved up or down upon the post orstandard 31, and thereby raise or lower the forward end of the beamsthrough the yoke 29 and curved bars 28, which connect this end of thebeams 21 with the head 30.

In the forward end of each beam is journaled a downwardly-projectingvertical standard 45. In rear of the standards 45 are arranged similarstandards 46, the upper ends of which are journaled in brackets whichpro ject laterally from the outer sides of each of the beams. Back ofthe standards46' are arranged other standards 47, which are journaled inthe beams 21. The standards 47 are similar to the first-mentionedstandards except that they project to a considerable distance above thebeams, as shown. In the rear ends of the beams are journaled stillanother pair of standards 48, which are of the same construction as thestandards 45 and 46.

On the lower ends of each of the standards 45, 46, 47, and 48 is fixed ahorizontal bearing or support 49, in each of which is journaled arevolving disk 50. These disks are arranged on the inner sides of thestandards and bearings 49 and are preferably flat, having their outeredges beveled to an edge,as shown. On each of the standards 47 arearranged upper and lower coiled springs 51 and 52, and on the upper endsof the standards are fixed crankarms 53, which retain the springs inplace. Above the standards 47 is arranged a curved bar 54, to which arefixed downwardly-projecting brackets 55, having forwardly-projectingright-angularly bent lugs 56, in which are formed openings through whichare adapted to pass the upwardly-extended ends of the standards 47. Thelugs 56 engage said standards between the upper and lower coiled springs51 and 52, as shown.

The curved bar 54 is slidably' supported by hangers 57, which consist ofinverted Tshaped plates 58, arranged on one side of the bar, and on saidplates are rotatably mounted an upper grooved roller 59, which engagesthe upper edge of the bar 54, and two grooved rollers 60, which engagethe lower edge of the bar, which connection permits said bar to slidelaterally in either direction. To the upper ends of the hanger-plates 58are loosely connected links 61, the upper ends of which are connected tothe forward ends of hand-levers 62, pivotally connected to the standard63 of segmental rack-bars 64, which are mounted on and securely bracedto the cross-bar 7 of the main frame. The segmental rack-bars 64 arefurther braced and connected together by a cross-bar 65, whichrotatablysupports the rear end of the inclined crank-rod 42. The hand-levers 62are provided with retainingpawls 66, which engage the rack-bars 64 andhold said levers intheir adjusted positions. The bar 54 yieldinglysupports the rear ends of the beams 21 through the brackets 55, whichengage the same between the springs 51 and 52. Upon the operation of thehandlevers said rear ends may be raised and lowered, as will beunderstood.

To each of the standards 45, 46, 47, and 48, between the upper and lowerbars of the beams 21, are respectively connected crank-arms 67, 68, 69,and 70. v The crank-arms 67 and 68 of the standards 45 and 46 arerespectively connected to the crank-arms 69 of the standard IIO 47 bylinks 71 and 72, while the crank-arm 7O which is pivotally connected alongitudinallydisposed lever 76, the forward end of which is slotted andhas a loose pivoted connection with the front arched bar 22. The rearends of the lever 76 is adapted to slide on the rear arch 23 and isconnected to a cable 77, which extends laterally in each direction andpasses downwardly over grooved guide-pulleys 78, journaled on the rearside of the rear arch 23. The lower ends of the cable 7 7 are adjustablyconnected to foot-levers 79, the forward ends of-which are pivotallyconnected to the sides of the front arched bar 22. The levers 7 9 arebent or curved laterally for a short distance to avoid interference withother parts of the machine, and the outer ends of the same pass througha guideway formed by the sides of the rear arched bar 23 and a rod orbar 80, arranged adjacent to and secured at its upper and lower ends tosaid sides. By depressing one or the other of the foot-levers the lever76 will be actuated to cause the bar 7 5 to turn the crank-arms 53 andthe standards 47, and through which motion will be imparted to the otherstandards to turn the disks carried thereby in one direction or theother to cause the soil to be thrown toward or from the corn.

In Fig. 6 of the drawings is shown a modified construction of thehangers 57 and the parts connected thereto. In this instance a hanger 81is provided, said hanger having two pairs of grooved rollers 82 and 83,the former being arranged below, the latter above, a round. bar 84,which is adapted to take the place of the bar 54 (shown in the otherfigures) and is curved to correspond with said bar 54. -Below the bar84- and spaced from the same is arranged a parallel bar 85, the ends ofwhich are bent upwardly and secured to the ends of the bar 84. To thebar 85 is loosely connected, as by pairs of short links 86, the upperends of downwardlyextending bars 87, which take the place of thebrackets 55 and are provided at their lower ends with right-angularlybent apertured lugs 88, through which are adapted to pass the upper endsof the standards 47, as shown and described in connection with the lugs56 on the brackets 55. The hangers 81 have each pivotally connectedthereto the lower ends of a link 89,- the upper ends of which arebifurcated, as shown, and are adapted to be pivotally connected to theoperatinghandles 62 to take the place of the links 61.

In Fig. 7 of the drawings is shown a detail vertical sectional View ofthe lower end of a disk-standard illustrating a modified construction ofbearing for the disk-hubs. In

this instance instead of the lower end of the standard and the bearingbeing cast in one piece said lower end of the standard is split upwardlya short distance, and said split ends are then bent laterally, as at 90,to form the upper portion of the bearing and laterallyprojecting ears orlugs 91, to which are bolted the laterally-projecting ears or lugs 92 ofa casting 93, forming the lower part of the hearing.

In Fig. 8 is shown a double form of hub 94, by which two disks may bemounted on the lower end of a standard, it being sometimes desirable touse this arrangement of disks on the two outer or rear standards 48. Inthis form of hub the two disks mounted thereon are disposed at an angleto each other, with their forward edges touching.

In Fig. 9 is shown an arrangement which may, if desired, be applied tothe disk-standards, whereby the bearings on the lower ends of the samemay be lubricated. This arrangement consistsin providing hollow ortubular standards closed at their upper ends by a threaded plug 91.Within the standards is disposed a plunger or piston disk 92, having athreadedaperture 93, said disk being mounted on a threaded rod 94, whichprojects down into the tubular standard and is screwed through thethreaded aperture of the plunger-disk 92. The upper end of the rod 94passes through an aperture in the plug 91 and is provided above andbelow said plug with stop-pins 95, whereby the rod is held from verticalmovement, but is permitted to turn freely in the plug. On the upper endof the rod 94 may be formed a suitable handle for turning the same. Theplunger-disk 92 isprovided on one edge with a notch 96,- which isadapted to engage a vertically-disposed rib 97, formed on the inner wallof the tubular standard, thereby preventing said disk from turning withthe rod, but permitting the same to be screwed up or down by reason ofits threaded engagement with the rod. In the tubular standard below theplunger-disk is placed grease or other suitable lubricant, which whenthe plunger-disk is screwed down will force said lubricant through afeed-opening 98 in the hub of the disk, and thereby lubricate the same.

In the drawings each beam 21 is shown as having mounted therein fourdisk-standards. I do not, however, wish to confine myself to thisnumber, as it is obvious that the length of the beams may be increasedand any desired number of disk-standards arranged therein, the samenumber being arranged in each beam.

I do not desire to limit myself to the use of my improved deviceshereinbefore described in connection with a wheel-cultivator, as thesame may be also used in connection with a walking-cultivator.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion,

' and the minor details of construction may be resorted to withoutdeparting from the principle or sacrificing any of the advantages ofthis invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
